A seventh-grader at Minnetonka Middle School West in Chanhassen has been charged with making terroristic threats after he showed a fellow classmate a list of "people I want to kill," authorities said this week.

The 13-year-old suspect, whose name was withheld because of his age, was arrested Tuesday evening and the iPad on which he wrote the since-deleted list was turned over to authorities for forensic examination, according to officials. The suspect appeared in court yesterday on charges of making terroristic threats, a felony, and fifth-degree assault, officials said.

In an email to parents, principal Paula Hoff said that school officials were notified of the incident by the mother of the other student, whose name appeared on the kill list. The incident reportedly occurred last Friday.

"We conducted an investigation and, following standard protocol in this type of situation, contacted local authorities," she wrote. "Situations like this may include suspension, expulsion and referral to law enforcement for prosecution."

Authorities gave no further details of the investigation, which they say is ongoing.

"We take these types of incidents very seriously and I will rigorously investigate every threat to the safety of our children," Carver County Sheriff Jim Olson said.
